CHARLES N. JACOBY, OF ROCHESTER, NEW YORK, ASSTGNOR TO RICHARDSON CORPORATION, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK.

AIPPARATUS FOR CARBONATING BEVERAGES.

To all whom it may concern:

Be it knownthat I, CHARLES N. lawn, a citizen of the United States of America, residing in Rochester, in the county of onroe and State of New York, have invented certain new and useful Improvements in Apparatus for Carbonating Beverages, of which the following is a specification.

My invention relates to a carbonating apparatus of the type adapted for carbonating a-beverage consisting of water and syrup. and has for its purpose to provide automatic means for accurately measuring the syrup, so that it is fed to the carbonating apparatus in definite metered quantities.

An instance of the application of the invention is the manufacture of root beer, which is sold to retailers in syrup form. It is the usual practice for the dealer to measure a certain quantity of syrup and a certain quantity of water, and place both of the measured ingredients into a single container, from which the mixture is fed to a carbonating machine, or otherwise to a discharge point, where it .is ready for consumption. lVith my invention it is unnecessary for the dealer to measure oil the syrup and water and thus form a mixture, and a great deal of time and trouble is thus eliminated. It is my purpose to employ a carbonating apparatus and to feed the water and syrup thereto from separate sources of supply. The proportion of syrup to water will be determined automatically by a metering or measuring device incorporated into the car- .bonating apparatus, and this insures always having a proper mixture, as predetermined by the operator, and as long as the supply of syrup and water continues. The syrup can be stored in any suitable tank or container, from which it is fed to the carbonating apparatus, and the only requirement as to syrup is that its container be filled at suflicient intervals to maintain a supply to the carbonating machine. My invention also makes it possible to utilize any city water supply, from which connection can be made directly to the carbonating apparatus, and this would under most circumstances be the most practical way of obtain- Specification of Letters Patent.

ing the necessary water supply, although obviously a tank or container for the water may be employed, the same as for syrup.

T 0 these and other ends, the invention consists in certain improvements and combinations of parts, all as will hereinafter be more fully described, the novel features being pointed out in the claims at the end of the specification.

Figure 1 is a perspective view of an apparatus, showing the application of my improvements;

Fig. 2 is a gearing;

Fig. 3 is a side elevation, partly in section, of the syrup metering device, and

Fig. 4 is a sectional. view taken on the line 4-4 of Fig. 3.

The mechanism disclosed, which is merely for illustrative purposes, includes a carbonating apparatus A, which may be of any conventional form having interior mixing devices, a suitable carbonic acid supply, and a discharge pipe B through which the carbonated beverage is forced under pressure to the oint of discharge, and I will now procee with a description of the novel features that have been incorporated in the apparatus of the general character just mentioned.

diagrammatic plan view of the C designates a water-supplying means consisting of a pipe which may be connected either with a water tank or with a city water supply. Where city water connection is utilized, a pressure regulator D is employed, and thence the water passes through pipe E to the pump, designated generally at F, and by which the water and syrup are forced into the carbonator.

Syrup is fed from a tank or other container by gravity through apipe G which or measuring device designated generally at H.. From the metering or measuring device H a pipe I leads to the pipe E already mentioned, where the syrup and water are brought together and fed to the carbonator. In order to properly proportion the supply of Water and syrup, the syrup is fed in predetermined and accurately measured amounts, and thepump is keyed in Figs. 1, 3 and upon the ratio of and syrup metering device are driven at redetermined relative speeds to accomp 1sh this.

The ump F is driven directly from a shaft which carries a driving gear L, and

the latter is operated from a pinion M which on the shaft of the motor N. The syrup-measuring or metering device H is controlled by a drivin gear 0 which is actuated b a pinion T on the aforesaid shaft K. y varying the relation ofv the gear and pinion O and P, the relative speeds of the mixture pump and syrup metering device can be changed to secure any proportion of syrup and water that may be desired, and this may depend upon the .nature of the beverage and of the syrup from which it is made. In ordinary practice for manufacturing a root beer beverage, the apparatus would be geared to feed one part of syrup to five parts of water, but these particular proportions are notessential to the purpose of the invention.

The syrup may be fed by any suitabledevice designed to definitely and accurately measure the syrup, and a convenient mechanism for carrying out my purpose is shown 4, in which Q designates a stationary casing or housing-adapted to receive an eccentrically-mounted carrier or disk R, the latterbeing suitably fixed upon the rotating arbor S which carries the aforesaid gear O. The carrier R is cut, away to receive 0 positely disposed pistons or blades T. he latter engage the inner periphery of the housing, as shown in Fig. 3,.

and are held apart, 1n proper relative position, by the intermediate spring U which is seated in recesses provided for the purpose.

As the pistons T rotate with the carrierR,

the syrup is metered, that is fed in measured amounts intermittently from the upper passage G into the lower passage I, and thence to the pipe E, as already described. A check valve, such as V, may be provided to prevent back pressure into the syrup feeding device.

In the operation of the structure, syrup is fed to the pipe G from any desirable source, and water to the pipe from any suitable supply, or from the standard water supply of a city, with which the apparatus can be easily connected. The pistons T of the syrup metering device measure and feed syrup into the pipe E in a definite, predetermined proportion to the water, dependent earing between the pinion P and gear 0. his gear ratio may cause the syrup metering device to operate once while the pump F completes five operations, for instance, thus taking in one part of syrup to every five parts of water. The mixture is then forced into the carbonator,

where it is thoroughly mixed and charged device controlling the supp with carbonic acid gas, as usual in this class 1 of apparatus.

The term syrup metering device, as used throughout this application, is intended to 4 refer to mechanism which permits a predetermined accurately measured portion of 7 syrup taking place in the carbonating a'ppa- 8 ratus.

Other modifications in the mechanism shown may be adopted without departing from the fundamental principleyof the invention, and the following claims are intended to cover any such changes as may come within the scopeof'the invention as herein defined.
